Netptune has 8 named moons (4 unnamed) and has large storms with the fastest winds of any planet in the solar system (2000 km/hr.).
The unit of frequency is the hertz (Hz), one cycle per second, named after Heinrich Hertz. For our purposes, we shall use much higher frequencies. One thousand Hz is a kHz (kilohertz); one thousand kHz is a MHz (megahertz); one thousand MHz is a GHz (gigahertz); one thousand GHz is a THz (terahertz).
hertz. A unit used to measure the frequency of vibrations and waves. One hertz is equal to one cycle per second.Radio waves are usually measured in megahertz, or millions of hertz., pl hertz. 1. (Units) the derived SI unit of frequency; the frequency of a periodic phenomenon that has a periodic time of 1 second; 1 cycle per second.
